TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 551,343, datedDecember'lO, 1895.

Application filed October 14, 1890.

To aZZ whom it may concern.-

Be it known that I, WARREN C. AoKLEY, a citizen of the United States,residing at the city of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention consists in certain features of construction andcombinations of devices hereinafter more fully described, andparticularly pointed out in the appended claims.

The object of the invention is to produce such an attachment fortype-writers as will automatically shift the feed of the printingribbon, so that when such ribbon has been wound upon one spool in onedirection the relative positions of parts of the mechanism will bealtered, so that the said ribbon will be wound upon the otherribbon-spool in the opposite direction, thus shifting the motion of theprinting-ribbon, automatically, from side to side, as the operatorprints with the machine. a

Figure 1 is an end View of part of a typewriting machine with myinvention attached Fig. 2 is a partly sectional view taken on the line yy of Fig. at. Fig. 8 is a partially sectional view taken on the line 2 2of Fig. 1. Fig. i is another partially sectional view taken on the line2 z of Fig. 1. Fig. 5 is another partially sectional view taken on theline 10 w of Fig. 1. Figs. 6, 7, S, 9, 10, 11, 12, 13, and l-LL aredetail views illustrating various parts of the invention more fullyhereinafter described.

In all the figures like numerals of reference denote similar parts ofthe mechanism.

In the example of my invention here given it is illustrated as adaptedto a Remington type-writing machine. It can, however, be adapted to manyother kinds of type-writers wit-h equal facility.

The numeral 1 designates the frame of the machine, and the 2ribbon-spools, which are mounted on the shafts 3. These shafts arejournaled at each side of the machine parallel to each other and in thecommon and well-known way.

i designates a sliding shaft, journaled in the machine in the same planewith the Serial No. 368,156. (No model.)

shafts 3, at right angles to and between them. Upon the shafts 3 aremounted the wheels '7 and 8. Upon the sliding shaft at are mounted thewheels 5 and 6. These wheels 5, 6, 7, 5 5 and 8 are all bevel-wheels,and are so arranged that when the shaft 4 is slipped one way the wheels5 and 8 will be engaged, and when the said shaft is slipped the otherway the wheels 6 and 7 will be engaged. \Yhen 6c the wheel 5 engages thewheel 8, the spools turn one way, and when the wheel 6 engages the wheel7 the spools turn the other way.

10 designates a post fastened to the frame of the machine, asillustrated. At the upper 6 5 end of this post is a sleeve, in which, asa bearing, turns a revoluble shaft. On the ends of this shaft aremounted the wheels 11 and 12. The wheel 11 is a plain disk-wheel,provided with the lugs 14, the form and arrange- 7o ment of which areillustrated in Figs. 6 and 7. The wheel 12 is a worm-wheel of disk formconstructed with teeth adapted to engage an endless screw, asillustrated in Figs. 8 and 9, the screwloeing mounted upon theribbon-shaft 3. 7 5 Upon the post 10, a little below the periphery ofthe wheel 11 and bestriding said wheel, is also pivoted a forkdesignated by 15. The prongs of this fork engage the lugs 14 of thewheel 11. These lugs, which are integralwith the wheel 11, are in theform of a right angle triangle prism, with one of the bases resting onthe side of the wheel. These lugs are formed on opposite sides of saidwheel, with their slanting faces in opposite directions, as 8 5illustrated. The distance between them is such that the fork isoscillated a little from side to side by the passing lugs. The outerprong of this fork is connected with the sliding shaft 4 by thespring-strap 13, so that go when the said fork oscillates it will slipthe shaft 4 a little endwise. This shaft 4 is propelled by the usualratchet mechanism.

If the mechanism be in the position illustrated in Fig. 4 as the machineis operated 5 the ribbon will be wound upon the left-hand spool andunwound from the right-hand spool, and at the same time, as the saidleft-hand spool turns, the endless screw 9 upon its shaft, engaging thewheel 12, will move the wheel through a distance equal to the pitch ofone tooth for each revolution of said spool; but

when the ribbon on the right-hand spool has been exhausted and wound onthe left-hand spool the mechanism will have carried the lug 1% around sofar that it will strike upon the inside prong of the fork 15. This willoscillate the fork a little, and in so doing, by means of theconnecting-spring 13, slip the shaft 4: endwise, so that the wheels 6and 7 will be disengaged and the wheels 5 and 8 come into engagement.This will causethe spools to move in the opposite direction and theribbon to be wound upon the right-hand spool. \Vhen the right-hand spoolis filled, the other one of the lugs It will be carried far enough inthe opposite direction to strike upon the outside prong of the fork 15and oscillate it in the opposite direction and in so doing slip theshaft a so that the wheels 5 and S will be disengaged and the wheels 6and 7 again come into engagement. The ribbon will then again wind on theleft-hand spool, and thus the ribbon will be shifted from side to sideas long as the machine is in operation. The stopping-latch 17, which isheld with its notch in the groove 18 by the spring 16, has the interioredges of its notch beveled, so that while it holds the shaft 4 inposition with sufficient steadiness it will at the same time not preventthe said shaft from being shifted. To further facilitate the shifting ofsaid shaft, the interior edges of the fork, where they come into contactwith the lugs 14:, are beveled, as illustrated.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

In a typewriting machine, the combination of an inking ribbon,ribbon-spools, gears for alternately turning said spools, and amechanism geared to one of said spools so as to be driven therebyprogressively and connected to the alternatelyacting spoolturning gears,and arranged to automatically shift the latter at or about the time theribbon has been unwound from one spool and wound upon the other, wherebythe direction of movement of the ribbon is mechanically reversed.
